Abstract
This study was conducted to investigate the isolation prequency, serotypes, and related epidemiological properties of 341 Salmonella spp from domestic poultry and environmental samples during the period 1993-1995. A total of 1,918 samples was collected during the three years period in nationwide. Most of Salmonella spp were isolated from the intestinal contents of poultry, especially cecal(46.0%) and rectal(35.8%) contents. Among the tested samples, rat(28.5 %) was the most predominant Salmonella reservoirs and followed by duck(24.8%), broiler(18.8%), layer(14.8%) and feed(7.1%), in order. More than twelve Salmonella serovars were identified among the 341 Salmonella isolates. The most prevalent serotypes isolated from non-human sources were S enteritidis (22.3%) and S pullorum (21.9%), S muenchen (13.9%), S typhimurium (12.6%), S gallinarum, S meleagridis, S heidelberg, and S senftenberg were followed, in order. In layer chickens, S pullorum (26.0%) was the most predominant serotype but S muenchen (33.0%) was in broiler chickens, S enteritidis (28.4%) was in ducks, and S typhimurium (60.0%) was in rats, respectively. As a results, S enteritidis was identified as the most prevalent serotype in non-human Salmonella isolates in Korea during the period 1993-1995. A preliminary study on the phage typing of 19 S enteritidis selected from the nationwide scale was shown that S enteritidis phage type(PT) 4 was the most predominant PT, and SEPT 1, SEPT 6a, SEPT 7 and SEPT 7a variant were also found in the same period.
